DISK PLOW.

SPECIFICATION forming part of Letters Patent No. 781,863, dated February'7, 1905 Application filed September 18, 1903 Serial No. 173,723.

To (1 71 117mm, 7% 71mg (roll/maria.-

Be it known that l, \VILI.L\.\1 N. ALLEN, a citizen of the UnitedStates, residing at Ironton, in the county of Lawrence and State ofOhio. have invented a new and useful Disk Flow, of which the followingis a specilication.

This invention relates to disk plows, and has for its object to simplifyand improve the construction and produce an implement of increasedstrength and utility without increase of expense or weight and which maybe more readily controlled and kept free from the accum ulations ofearth when employed in sticky or wet soil; and the invention consists incertain novel features of construction, as hereinafter shown anddescribed, and specified in the claims.

in the drawings illustrative of the invention. in which correspondingparts are denoted by like designating characters, Figure l is a planview, partly in section, of the improved device. Fig. 2 is a sideelevation of the rear portion of the device. Fig. I) is a sectionaldetail illustrating the manner of connecting the cutting-disk to itsrotative support. Fig. T is a perspective view of the disk-holding boltdetached. Fig. is a transverse section, enlarged, on the line 5 5 ofFig. 3. i

The improved implement consists ofa main supporting-frame 10, having abracket ll at the forward end, to which the draft-tongue 12 is attached.and cari ving the frame 13 of the forward furrow-wheel 1% and a bracket15 for the landwheel lb. The furrow-wheel 1i and land-wheel 16 areprovided, respectively, with adjusting mechanism (represented at l7 18)of the usual construction; but as those portions of the implement arenotanovcl feature of the present invention they are not fur therillustrated, as the construction of such devices is so well known.

r-Xttached to the face of the inclined portion 19 of the frame is abracket 20, upon whose lower side a transverse sleeve 21 is formed, thesleeve 21 supporting a stud 22 for rotation therein, the stud having aconcaved plate 1 2;") on its outer end engaging the convex side of aconcave-convex cutting-disk 24-. The

plate 23 and its stud are provided with a central aperture, the wallsofthe outer end of the aperture being flared and provided with spacedcorrugations in the sides of the flared portion and the disk 2% beingformed with a correspond ing central aperture surrounded by a conicalextension 25, conforming to the flared cavity in the plate 2;; andcorrespondingly corrugated. Fitting the aperture in the parts 22 23 A isa clamp-bolt as, having a conical outer end 27, corrugated to correspondto the corrugations in the members 23 and 25. By this simple arrangementit will be obvious that when the nut 28 is set up on the bolt 26 thedisk 2% will be lirmly and immovably clamped to the plate 23 androtative with the plate and its stud in the sleeve L1. The disk is thusvery lirmly united to the plate by one single bolt, with the strainsdistributed over a relatively large area by means of the corrugatedconical extension and corresponding conical corrugated cavity in theplate 3. The disk is thus not only lirn'ily held in position, but iseasily detachable when rei' uired for renewal or repairs bysimplyrcleasing the one bolt 26. The corrugations thus serve a very importantpurpose and materially increase the strength of the joint between theparts.

Attached to the outer face of the bracket is a standard Lt), projectinghorizontally at the upper end and provided with a clampbolt 31, engaginga li'mgitiulinal slot 32 in an extension-bar 33, the latter terminatingin a curved head I) having a clampbolt 35. The extension member 33 isthus longitudinally adjustable upon the standard 29.

Engaging the concave face of the disk A is a scraper 36, from which anarm 37 extends, as shown, and extending longitiulinally of the arm 37 isanother arm, 38, connected adjustably to the arm 37 by a slot 39 andboltiO, as shown. The extension-arm 3S terminates at its free end in acurved portion Tl. corresponding to and engaging the curved portion 2%of the member 3?). The portion ii is provided with a longitudinal slot4C2, through which the clamp-bolt passes, as shown, to provide for theadjustment between the parts 33 and 3b, with the bolt 38 holding itagainst lateral movement. By these numerous ad- Lil justments thescraper 86 may be adapted to the face of the disk 24 and adjusted to allthe variations which may occur therein.

At the rear of the frame-section 19 is a bracket 43, having a verticalsocket in which a stud 44 on a hanger-frame 45 is rotatively supported,the hanger-frame carrying the rear furrow-wheel 46, the latterpreferably set at an angle to the frame 10 19, as shown, andoperating inthe furrow in the rear of the disk in the ordinary manner. The frame 45is thus free to swing laterally of the main frame and to hold it inoperative position in the furrow. A bolt 47 is disposed in the bracket43 with its lower end extending into the path of the frame. The bolt 47has combined with it an operating-lever 48, pivoted at 49 to the bracketand adapted when depressed, as by the foot of the operator, to elevatethe bolt 47 and release the frame 45. By this arrangement it will beobvious that when the bolt 47 is in its downward or operative positionthe frame 45, with its attached furrow-wheel, will also be held inoperative position or with the furrow-wheel in the furrow. hen it isdesired to turn the plow at the end of the furrow, a simple pressure ofthe foot of the operator will release the frame and permit thefurrow-wheel to swing later ally and trail after the disk, and thuspermit the plow to be moved in a curve or turned around to any desiredextent. IVhen the plow is again brought into operative position, theframe 45 will be restored to its former place. By this simplearrangement the plow can be moved in any desired direction withoutcramping the parts or imposing unnecessary hardship or labor on thedraft-animals.

The parts can be constructed of any required size or of any suitablematerial and will be found very convenient in use, easily operated andcontrolled.

Stop-lugs 5O 51 will be employed upon the bracket 43 to limit thelateral movement of the hanger 45.

A seat-bracket 52, supporting a seat 53, will be connected to the frame,as shown.

Having thus described my invention, what I claim is 1. In a plow, a mainframe carrying a turfturning element, an auxiliary frame mounted toswing laterally on said main frame in the rear of said turning elementand carrying a furrow-wheel, a bolt mounted to slide vertically with oneend depending normally into the path of said auxiliary frame, a levermovahly mounted on said main frame and connected with said bolt, andabutments on the main frame for limiting the lateral movement of theauxiliary frame.

2. In a plow, a frame carrying a cuttingdisk, an upright standardextending from said frame and provided with a lateral extensionadjustable longitudinally thereof, a scraper operative against the faceof the disk and having an arm extending upwardly therefrom and providedwith an extension adjustable longitudinally thereof, the free ends ofsaid stand ard extension and scraper-arm extension being correspondinglycurved and with the curved portions adjustabl y connected,substan tiallyas described.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.
